This week

Eyes open for the first time.

  • First glimpses
    The eyelids, fused since the first trimester, open, and the eyes begin to blink.
  • Dream sleep begins
    Brain activity now shows REM sleep, the phase in which we dream.
  • Breathing rehearsals
    Regular practise-breathing movements strengthen the muscles that will work from the first cry.
